+ * #CallyUtil implements #AtkUtil abstract methods. Although it
+ * includes the name "Util" it is in fact one of the most important
+ * interfaces to be implemented in any ATK toolkit implementation.
+
+ * For instance, it defines atk_get_root(), the method that returns
+ * the root object in the hierarchy. Without it, you don't have
+ * available any accessible object.
